Hey guys- >With the new Notch engine the hot oil pressure is about 5lbs lower than it >should be...well, when compared with a stock engine. Im running full flow >on the Notch and I was told by a mechanic locally here that there have been >issues with pressure drops over the Fram oil filters. Well, from memory I can tell you that Shad had some issues with low oil pressure at idle when warm and we solved them by replacing the shadeck (sp?) aluminum body oil pump with a cast iron pump which we blueprinted till we were blue in the face (pun not intended). Oil pressure is no longer a problem, regardless of rpm. With oil temps over 200F we often see pressures over 60 psi at rpms as low as 2k rpm (if my memory serves correctly). Shad- chime in here and clarify those numbers for me. >Are fram too restrictive? is there a better brand to use that is less? >what should I expect in pressure reduction? Shad and I have done lots of research and testing on oil filters and we both would have to agree that the PureOne oil filter has very good filtration and a very high quality of manufacture, but we have as of late played around with K&N's oil filters and found them to be superior in many respects. (http://www.knfilters.com/oilfilter.htm) They claim 550 psi burst strength, synthetic media filter, anti-drainback valve, rolled threads (kinda overkill here), and a leak-proof double rolled seam. Best of all, the K&N filter filters as well as PureOne and its competitors. Only drawback here is the $9.00 price tag. Another filter of equal quality (and of equal price) is the Mobil 1 filter.
